Dave Wannstedt has agreed to become the new assistant head coach and linebackers coach for the Buffalo Bills, Fox Sports' Alex Marvez reported Friday. Wannstedt interviewed with the Browns to become their defensive coordinator on Thursday, a league source said.

Wannstedt, who was forced out as head coach of the University of Pittsburgh football team last month, is the third coordinator candidate known to have ended up with another team after interviewing with the Browns. The Browns also pursued Mike McCoy and Bill Musgrave to fill their offensive coordinator vacancy, but McCoy stayed with the Denver Broncos and Musgrave accepted a job offer from the Minnesota Vikings.

With Wannstedt, 58, out of the mix, Dick Jauron, 60, and Bill Davis, 45, appear to be the top candidates to replace Rob Ryan, who is now the Dallas Cowboys' defensive coordinator. Jauron interviewed with the Browns on Tuesday and Wednesday, a league source said. Davis met with the team Thursday, ESPN's Adam Schefter reported. Jauron is now believed to be the front-runner to fill the Browns' opening, Marvez reported.

Jauron and Davis are also candidates to become the Philadelphia Eagles' defensive coordinator. Jauron uses a 4-3 defense, and Davis uses a 3-4.
